Characterization of a titanium coaxial condenser
(North-West University (South Africa)., 2020)In South Africa a leading engineering company, focusing on energy engineering services and products to the mining industry, developed a mobile refrigeration unit known as the air-cooling unit (ACU) MKII. The ACU MKII uses ... -
Characterization of an alginate encapsulated LS180 spheroid model for anti-colorectal cancer compound screening
(ACS, 2020)Colorectal cancer is one of the leading causes of cancer-related deaths. A main problem for its treatment is resistance to chemotherapy, requiring the development of new drugs. The success rate of new candidate cancer drugs ... -
Characterization of bacteria isolated from a platinum mine tailings dam
(North-West University, 2012)Contamination from various sources has a huge impact on soil health and microbial community composition. Metal contamination of soil in mining scenarios is of concern and is not adequately addressed, particularly with ... -
Characterization of circulating DNA as a biomarker for genetic aberrations in humans
(North-West University, 2006)Circulating DNA is fragments of DNA which can be found in the blood of healthy as well as diseased individuals. Higher levels of these nucleic acid molecules can be found in diseased and pregnant individuals in contrast ... -
Characterization of circulating free DNA in healthy and diseased individuals
(North-West University, 2009)Circulating DNA is small fragments of DNA present in the blood of vertebrates. Even though the origin, function and significance of these DNA fragments are not elucidated yet, it is widely investigated as a source of ... -
Characterization of Clostridium spp. isolated from selected surface water systems and aquatic sediment
(North-West University (South Africa), Potchefstroom Campus, 2017)Clostridium are ubiquitous in nature and common inhabitants of the gastrointestinal track of humans and animals. Some are pathogenic or toxin producers. These pathogenic Clostridium species can be introduced into surface ... -
Characterization of Clostridium, Aeromonas and heterotrophic bacteria in selected groundwater systems
(North-West University (South Africa)North-West University, 2020)Water sources in the North West Province (NWP) are made up of groundwater, surface water and re-useable effluent. However, major water challenges are experienced in the NWP when quality and quantity are considered. The NWP ... -
Characterization of ecological risks from environmental releases of decamethylcyclopentasiloxane (D5)
(Wiley, 2015)Decamethylcyclopentasiloxane (D5) is used in personal care products and industrial applications. The authors summarize the risks to the environment from D5 based on multiple lines of evidence and conclude that it presents ... -
Characterization of enterococci isolates from water sources in the North West Province
(North-West University (South Africa), 2016)Enterococci are a diverse and complex group of ubiquitous bacteria that can survive extreme conditions. Despite constituting a large portion of the gastrointestinal tract in warm blooded animals and humans, they are ... -
Characterization of equine cytochrome P450: role of CYP3A in the metabolism of diazepam
(Wiley, 2016)Research on drug metabolism and pharmacokinetics in large animal species including the horse is scarce because of the challenges in conducting in vivo studies. The metabolic reactions catalyzed by cytochrome P450s (CYPs) ... -
Characterization of function and genetic feature of UDP-glucuronosyltransferase in avian species
(Elsevier, 2019)Birds are exposed to many xenobiotics during their lifetime. For accurate prediction of xenobiotic-induced toxic effects on avian species, it is necessary to understand metabolic capacities in a comprehensive range of bird ... -
Characterization of heavy metal tolerant bacterial plasmids isolated from a platinum mine tailings dam
(North-West University, 2012)The development of metal-tolerance and antibiotic resistance in bacteria may be caused by metals polluting a particular environment. During mining and mineral processing activities, large quantities of metals are deposited ... -
Characterization of heterotrophic plate count (HPC) bacteria from biofilm and bulk water samples from the Potchefstroom drinking water distribution system
(North-West University, 2009)The presence of heterotrophic plate count (HPC) bacteria in drinking water distribution systems is usually not considered harmful to the general consumer. However, precautions must be taken regarding the immunocompromised. ... -
Characterization of lignosulphonate and its changes during purification
(North-West University (South Africa)., 2023)The world needs an environmentally friendly renewable resource that could satisfy future energy needs and lower the impact on climate change. This need has driven many countries to fund research into biomass and biomass ... -
Characterization of microbial assemblages on micro-plastics in a river system
(North-West University (South Africa), 2021)Microplastics as pollutants originate from land-based sources and are persistent and ubiquitous in the aquatic environment. The risks posed by microplastics as vectors and habitats for potentially harmful microbial groups ... -
